A reason why conventional mining is not possible anymore can be flooding in the mine, too much folding encountered or high occurrence of methane gas in the deposit (Encyclopedia of Chemical Processes and Design, vol. 41, 1992). The principles of the solution mining process are that water or an unsaturated solution of potassium chloride is passed through a system of


Ages of exploitable potash deposits range from Quaternary to Devonian; no economic potash deposits are known to occur in Precambrian strata. Most exploited potash is derived from sylvinite ores although carnallitite slurries are processed in the Dead Sea Salt Works. Even though the various potash salts are highly soluble. subsurface solutions cannot alter them

mineral deposit - Hydrothermal solution | Britannica

Those solutions that do form mineral deposits (and thereby leave obvious evidence of their former presence) do so because some process causes them to deposit their dissolved loads in a restricted space or small volume of porous rock. It is most convenient, therefore, to discuss hydrothermal mineral deposits in the context of their settings. Veins. The simplest

The method of obtaining potassium chloride from sylvinite ores

Ground sylvinite ore is dissolved in recycled potassium chloride-saturated lye. Resulting solution is directed at a rate of m/s to leaching in the first dissolution column, with its electrodes connected to one of a current source poles, and treated by low-frequency (1-5 Hz) alternating electric field at voltage 30-100 v. Solution thus

It is an inexpensive bulk mineral also known as halite which can be found in concave rocks of coastal areas or in lagoons where sea water gets trapped and deposits salt as it evaporates in the sun. The most important salt minerals, which produced by solution mining are: Rock salt (or Halite) (NaCl) Sylvinite (NaCl + KCl) Carnallite (KMgCl3*6H2O or MgCl2 * KCl * 6H2O) Trona

Intensification of potash ores flotation desliming

The article presents the results of laboratory and pilot tests of technology for flotation desliming of sylvinite ores from Verkhnekamskoye potash deposit. Studies have shown that the flotation of slime used for the benefication of the water-soluble mineral by reagents — collectors of slime in the water — almost does not go. But even at low salt concentrations (–%) an increase in
